Blender 4.4
Among the many professional Open Source software, one of the most famous for 3D modeling is certainly Blender, now in its 4.4 version. Those who think of open source software as software that cannot compete with proprietary ones will have to think again when using Blender.
It is a cross-platform software for rigging, animation, compositing and 3D rendering.
Born in 2002, the main features are listed below as per source https://formazione.blender.it/conoscere-blender
Blender Features
Blender requires little space to install and can run on many platforms. Although it is often distributed without documentation or examples, the software is rich in features typical of advanced modeling systems. Among its potential, we can mention:
Support for a wide variety of geometric primitives, including polygon meshes, Bézier curves, NURBS, metaballs, and vector fonts;
Conversion to and from numerous formats for 3D applications;
Tools to manage animations, such as inverse kinematics, armatures (skeletons) and lattice deformation, keyframe management, nonlinear animations, constraints, weighted vertex calculation and particle management mesh capabilities;
Non-linear video editing management;
Versatile internal rendering engine such as Cycles and EEVEE and native integration with the external engine LuxCoreRender (an open source raytracer);
Sculpt system for modeling 3D objects and Grease Pencil for drawing in 2D in a 3D environment;
Python scripting to automate and/or control many aspects of your program and scene.

Blender 4.4 represents a major leap forward in the world of 3D creation . Among the most exciting new features are a significant improvement in material management , thanks to the introduction of new shaders and greater integration with rendering engines . The new user interface has been designed to be more intuitive, allowing artists to easily navigate between features without distractions. In addition, the new version offers advanced tools for digital sculpting , making the creative process even more fluid. Animation functions have been expanded, with new options for creating realistic and dynamic movements. Another notable innovation is the enhancement of simulation capabilities, which now include fluid effects and fabrics with unprecedented visual quality. Blender 4.4 also supports new import and export formats, making it easier to collaborate between different software and workflows. Finally, the Blender community continues to grow, and with it a myriad of resources and tutorials to help new users get the most out of this powerful tool. With these new features, Blender 4.4 confirms itself as one of the most versatile and powerful tools in the 3D graphics panorama.
In short, Blender is certainly a very powerful tool and the fact that it is Open Source should push more and more people to use this software in the professional world to take power away from the large multinationals in the sector.
